Business Rule - for enforcing Max Length on a String Field

[Elizabeth26]

I need to set a string field to a max length of 13,000 characters. It currently does not enforce this.

I was thinking of doing this in a business rule - does anyone have any scripting/code for this?

I need something like this" You can create a business rule on the table with the field, to run on insert/update. and then truncate that field's value to the desired length. Defined the business rule to run "Before"."

I have set the max length to 13,000 but it does NOT enforce anything that exceed 255 characters - it is a bug/feature from ServiceNow and this is what their support recommended.

Hi Elizabeth,

You could simply right click the field label > Configure Dictionary > set the Max length to 13000. If you need to alert the user of the max length or something like that, then it is a slightly different story. That is when you need to write script and such..
